所以要做你想做的事情：
radioButtonGroup.setOnClickedButtonListener(new RadioRealButtonGroup.OnClickedButtonListener() {
@Override
public void onClickedButton(RadioRealButton button, int position) {
switch (button.getId()) {
case R.id.radioBtn_dialog_addDriverState_offDuty:
DRIVER_STATE = DriverLog.STATE_OFFLINE;
radioButton_offduty.setEnabled(false);
radioButton_onduty.setEnabled(true);
radioButton_sleeper.setEnabled(true);
radioButton_driving.setEnabled(true);
radioButton_yard.setEnabled(true);
radioButton_personal.setEnabled(true);
break;
case R.id.radioBtn_dialog_addDriverState_onDuty:
DRIVER_STATE = DriverLog.STATE_ONLINE;
radioButton_offduty.setEnabled(true);
radioButton_onduty.setEnabled(false);
radioButton_sleeper.setEnabled(true);
radioButton_driving.setEnabled(true);
radioButton_yard.setEnabled(true);
radioButton_personal.setEnabled(true);
break;
case R.id.radioBtn_dialog_addDriverState_sleeperBerth:
DRIVER_STATE = DriverLog.STATE_SLEEPER;
radioButton_offduty.setEnabled(true);
radioButton_onduty.setEnabled(true);
radioButton_sleeper.setEnabled(false);
radioButton_driving.setEnabled(true);
radioButton_yard.setEnabled(true);
radioButton_personal.setEnabled(true);
break;
case R.id.radioBtn_dialog_addDriverState_driving:
DRIVER_STATE = DriverLog.STATE_DRIVING;
radioButton_offduty.setEnabled(true);
radioButton_onduty.setEnabled(true);
radioButton_sleeper.setEnabled(true);
radioButton_driving.setEnabled(false);
radioButton_yard.setEnabled(true);
radioButton_personal.setEnabled(true);
break;
case R.id.radioBtn_dialog_addDriverState_yard_move:
DRIVER_STATE = DriverLog.STATE_YARD_MOVE;
radioButton_offduty.setEnabled(true);
radioButton_onduty.setEnabled(true);
radioButton_sleeper.setEnabled(true);
radioButton_driving.setEnabled(true);
radioButton_yard.setEnabled(false);
radioButton_personal.setEnabled(true);
break;
case R.id.radioBtn_dialog_addDriverState_personal_conveyance:
DRIVER_STATE = DriverLog.STATE_PERSONAL_CONVEYANCE;
radioButton_offduty.setEnabled(true);
radioButton_onduty.setEnabled(true);
radioButton_sleeper.setEnabled(true);
radioButton_driving.setEnabled(true);
radioButton_yard.setEnabled(true);
radioButton_personal.setEnabled(false);
break;
}
}
});
